Answer:

The number of sides is 7

Explanation:

Once the sum of interior angles is equal to 900º and the sum of interior angles is given by


S=(n-2) \cdot 180\º, \text{ as }n \text{ being the number of sides}


900\º = (n-2) \cdot 180\º


(900\º)/(180\º) = (n-2)


5 = (n-2)


5+2 = n-2+2


\boxed{n=7}
